A man ordered to spend more than a decade in prison for his role in the death of a Plymouth resident is appealing his sentence, arguing he doesn’t deserve such a long prison term.
Nappanee-based attorney Alex Hoover filed the appeal for Maeson Coffin, 20, of Plymouth, late last week.
Marshall Superior Court I Judge Robert Bowen sentenced Coffin in February to 15 years total behind bars after Coffin pleaded guilty a month earlier to burglary, auto theft and theft as part of an agreement with the Marshall County Prosecutor’s Office.
As part of the plea deal, charges of conspiracy to commit murder and murder were dismissed.
Coffin’s co-defendant in the case, Gauvin Monaghan, 19, of Watertown, N.Y., pleaded guilty in November to a single count of murder in connection with the beating death of Richard P. Costello, 78, in October 2016.
Bowen sentenced Monaghan in December to the maximum term, which is 65 years.
In an agreement with the prosecutor’s office, charges of conspiracy to commit murder, auto theft, burglary and theft were dismissed against Monaghan.
Prosecutors have said Monaghan killed Costello and Coffin then helped hide Costello’s body. The two then stole items from Costello’s home before taking his vehicle and fleeing the state.
In his appeal, Coffin argues his sentence was too lengthy based on his character and his limited role in Costello’s death.
